A linear scale height Chapman model supported by GNSS occultation measurements
(2016-05)
Conference lecture
Open AccessGlobal Navigation Satellite Systems (GNSS) radio occultations allow the vertical sounding of the Earth's atmosphere, in particular, the ionosphere. The physical observables estimated with this technique permit to test ... -

Comparing performances of seven different global VTEC ionospheric models in the IGS context
(International GNSS Service (IGS), 2016)
Conference report
Restricted access - publisher's policyA summary of the main concepts on Global Ionospheric Map(s) (hereinafter GIM(s)) of Vertical Electron Content (VTEC), with special emphasis on their assessment, is presented in this paper. It is based on the experience ... -
Computation of analytical solutions of the relative motion about a Keplerian elliptic orbit
(2012-01)
Article
Restricted access - publisher's policyThe purpose of this paper is to obtain a third-order expression, for the in-plane and out-of-plane amplitudes, of the solutions of the elliptic Hill–Clohessy–Wiltshire non-linear equations. The resulting third-order solution ... -

Dynamical behavior of asteroids near resonance: the 4:1 gap and the 7:2 group
(1999-08)
Article
Restricted access - publisher's policyA comparative study of the evolution of the Sun–Jupiter–Asteroid system near the 4:1 and 7:2 resonances is performed by means of two techniques that proceed differently from the Hamiltonian corresponding to the planar ... -
